1. Introduction

Hello from Japan! 🇯🇵

I am an active truck driver in Japan self-studying Python, leveraging my logistics domain knowledge to become a Web Engineer.

(English is my second language, but I'm excited to share my journey with developers around the world!)

I started my self-study journey on May 12, 2026. In this article, I summarize the process of deploying Ruby on Rails 8 to a PaaS (Render Free Tier) and how I tackled the strict resource constraints I ran into.
